Distribution Block Specifications

Distribution Block Type

This specifies what the intended use of the distribution block is. Fused distribution blocks are intended to be used with the power wire and the fuse acts as a short-circuit or surge protection so your amplifier is not as likely to be damaged. Non-fused distribution blocks can used with ground or power wire connections, but the protection on power wire connections will not be present as there is no fuse in the distribution block. Therefore, we recommend your amplifier has an external fuse for short-circuit or surge protection. When using either type of distribution block, it is recommended to use a main fuse holder within 18 inches of the battery.

Fused

Total Number of Inputs

This is the total number of input connections that go into the unit.

Maximum Input Gauge Size

This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.

Fuse Type

For accessories, this is the type of fuse that is required for the item to work properly.

Generally good quality distribution block, however I consider it to have a major flaw in that it uses phillips head screws that both strip very easily and do not stay properly tightened, so your wires will randomly come out of the sockets. Personally, I'm going to see if i can find hex screws of relative sizes to replace the stock screws because I'm getting sick of constantly trying to tighten down the screws (and strip them in the process).
